1. Magnetic Resonance Imaging (MR)is a noninvasive imaging technology that is known for its superior soft tissue contrast and ability to provide morphological, microstructural, functional, and metabolic information.
2. MRI does not involve X rays and the use of ionizing radiation, which distinguishes it from CT or CAT scans.
3. MRI is the investigative tool of choice for neurological cancers, as it has better resolution than CT and offers better visualization of the posterior fossa. The contrast provided between grey and white matter makes MRI the best choice for many conditions of the central nervous system, including demyelinating diseases, dementia, cerebro-vascular disease, infectious diseases, and epilepsy. MRI's Cardiac aplicatins indude assessment of myocardial ischemia and viability, cardiomyopathies, myocarditis, iron overload, vascular diseases, and congenital heart disease.
